    en.wikipedia.org/wiki/Radio_beacon

    In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. But instead of employing visible light , radio beacons transmit electromagnetic radiation in the radio wave band .

  6. Air traffic control radar beacon system - Wikipedia

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."

  7. Lorenz beam - Wikipedia

    en.wikipedia.org/wiki/Lorenz_beam

    Lorenz-System Guidance Beam Landing Radio Beacon. Lorenz used a single radio transmitter at 33.3 MHz (German: Anflugfunkfeuer, lit. 'approach radio beacon') and three vertically polararized antennas placed in a line parallel to the end of the runway. The center antenna was always provided with the RF signal, while the other two were short ...

  8. Ramark - Wikipedia

    en.wikipedia.org/wiki/Ramark

    A ramark, syllabic acronym for radar marker, was a type of radar beacon used to mark maritime navigational hazards. Ramarks are no longer in use. Ramarks are a non-directional, continuously transmitting radar beacon which indicate the bearing to a navigational hazard when viewed on a radar plan position indicator (PPI) display. [1]

  9. GRAVES (system) - Wikipedia

    en.wikipedia.org/wiki/GRAVES_(system)

    Using radar measurements, the French Air and Space Force is able to spot satellites orbiting the Earth and determine their orbit. The GRAVES system took 15 years to develop, and became operational in November, 2005. [2] GRAVES is also a contributing system to the European Space Agency's Space Situational Awareness Programme (SSA). [3]
